SPECIFICATION forming part of Letters Patent No. .291,-r (23, Caied January 1, 1.854.

` l Application tiled january 29, 1853. (Model.)

To lf/ZZ whom, ib may concern.-

Be it known that I, 'GEORGE W. CURRY, a citizen of the United States, residing at St. Louis and State of `Missouri, have invented a new and useful Improved Sash-Lock, of which the following is a specification.

"My invention relates to improvements in sash-locks; and the objects of my improvements are, lirst, to provide an automatic or self -closing sash-lock; secondly, to afford a safe, secure, and reliable `burglar-proof sashlock which can be easily applied to all Window-sashes, will prevent theirsagging, rat` tling, &c., and which will otherwise possess advantages of simplicity, strength, and durability in construction, reliability in operation, and

convenience for proper handling of the sashes. I attain these objectsby the mechanism illustrated 'in the accompanying drawings, in.n

i sashes.` Fig. 3 is a bottom plan of the sashlock to better show its interior mechanismas the parts appear when the'lock is closed. Fig. 4 is a similar view of the under side or bottom of the sash-lock, representing the same internal operating parts when in open position. Fig. 5 is an edge view of thelock to show the thumb-lever in itsllocked position, not only by its lug with the top face of the socket plate' or catch. but having its arm atthe same time in `engagement with the mortise under the bevel-face ofthe catch..v Fig. 6 is a face view or elevation of the socket plate or catch, which is the only portion of the sash-lock that is fastened, and remains part ot' the face of the outer sash.` Fig. 7 is an edge View of the lock-casing,1with its bolt-opening, and edge vievr of thesarm of the thumb-lever, having alug onits under face. Fig. 8 is a central sectional ele-` vationA on line 8 8 through the entire sashlock when in locked condition.` Fig.'9 is a bottom plan of the swinging or thumb lever. Fig. 10 represents `both faces of the sashes to which the lock is applied, the inner sash having an offset orportion cut away. p

n Similar letters refer to similar parts throughout the several views.

I willirst describe that portion of the sashlock that is applied to and remains part of the inside sash.

A represents the casing to contain the operating parts. The outer wall,.A, ot' the casing, has the opening a, through which the bolt passes, and at a the casing has a shoulder above the line of thetop face of the casing. (See Figs. 7, 8.) l

b represents the spindle passing through the casing A, and fitted to partially turn in same. tSee Figs. 3, 4, 8.)

My, sliding bolt consists of the tongue or' bolt c, proper, projecting from a bearing-plate,

c', that has the mortise or slot c2, as clearly shown in Figs. l, 2, 4, 8.

The spindle passes through the slot in the bearing-plate c; hence the latter can be itted to slide in the top of the casing A, the slot c2 freely permitting the said bearingplate and.` Its bolt to be moved backward and forward for purposes of locking and unlocking the sashlock.

I have provided the following automaticacting parts to aotuate the sliding bolt to enter and be locked in engagement with the catch on the outer sash, or be unlocked, as the case may require. x

l D is an arm secured to and turning with th lower end of the spindle. The outer end of the arm D is pivotedto a connecting-arm, D',

which in turn has its outer end pivoted to the shank ofthe bolto. (See Figs. 3, 4.) Hence. by partially turning the spindle, the arms D D can be moved to draw the bolt c inward, and when completely drawn inward, `so as to clear thecatch on the outer sash, the parts are in ghelopen or unlocked condition shown in Figs. A, a

To automaticallycosc or lock the bolt parts,

I simply provide the spring E, having one end` bearing against the spindle-armD, the other end of the sprlng being fastened to the casing at e, as shown 1n Figs. 3, 4. As soon as the spindle is released the spring restores the bolt' `and its parts to a locked condition..` Consef quently the arms D D and bearing-plate :are e" is` also in original position. (See Fig.` 3.)

a stop to limit the movement or the arm D to its proper piace. (See Figs. 3, 4.) .i

F is the thumb-lever, by means whereof the operator slides back the bolt or opens the sash-lock. This thumb-lever has the central socket, f, the downward-projecting arm f', and the lateral arm f2, as shown in Figs. l, 2, 5, 8, 9. By its sockets f the thumb-lever is keyed to the top of the spindle to operate the latter. By its projecting or lateral arm f2 the locking of -the thumb-lever with the mortise of the catch on the outer sash is effected, for purposes hereinafter stated. Further, the arm f2 has the lugj'3 to engage the shoulder of the catch on the outer sash, for purposes as will hereinafter appear.

The above-described parts constitute that portion of the sash-lock that is secured to the inside window-sash. The remaining portion of the sash-lock is secured to the outer sash, and consists simply of the catch G. This catch G consists, in its entirety, of a single casting, of the constructive shape shown in Figs.v l, 5, 6, 8, and has the specific features, viz: the bevel-face at g, the mortise at g', the shoulder at g2, the socket g3, all as shown. It is against the bevel-face g that the arm f2 of the thumb-lever strikes against in the act of lowering the inside sash, the said bevel-face causing the thumb-lever, as it descends, to be thrust or turned to one side, as will hereinafter appear. In the mortise g the arm f2 of the lever enters to lock the sash-lock parts at saidnamed place. The shoulder at g2, in conjunction with the lug f3 ofthe lever, forms the third locking feature of importance in preventing the lock from being separated or pried apart by any endeavor to separate the sashes. The socket g3 isthe catch proper to receive the bolt c, and when the latter has been locked in the former the window-sashes are securely locked against any attempt to raise the lower sash.

The sash-lock thus constructed I apply to the two sashes X X, as follows: As shown in Figs. l, 2, 8, I secure to the outer sash, X', the 4catch G, so that it partially projects beyond the dividing-line of the sashes. Thus, let w represent the line dividing both sashes. I secure the catch G so that its bevel-face catch g and shoulder g2 project to the inside or over a portion of the inside sash, X; hence, as the said projecting parts of the catch G would interfere with the raising and lowering of the inside sash, the latter is mortised, or has that portion thereof cut away, as indicated by the letters x. (See Figs. 8, l0.) Both portions of the sash-lock having thus been secured, respectively, to the meeting-rails of the sashes, (see Figs. l, 2, 8,) the complete operation of the sash-lock is as follows: By referring to Figs. 1, 3, 5, 7, 8, the sash-lock is represented in full-locked condition, preventing the sashes from being operated. It will be noted that the thumb-lever has its armj2 in engagement with the mortise r/ of the catch G under its bevel-face at same time the lug f of the thumb-lever'is behind the shoulder g2 of the catch. Said locking features prevent the prying apart of the sashes, and render the sashlock burglar-proof. At the same time the strong boltc is locked in the socket of the catch G, which prevents any forcible raising of the inside sash. To open the sash-lock the thumb-lever F is turned fully to one side, (see Fig. 2,) which disengages its arm f2 from the bevel-face catch g, also releases its lug]c3 fiom the shoulder of the catch G, hence unlocking all the lockingfdevices that' exist top of the casing. At the saine time the lever is so turned to one side that it actuates the spindle by its two arms, D D, to Withdraw the bolt c out of the catch G, and the sash-lock being in the unlocked position shown in Figs. 2, 4, the sashes can be freely raised or lowered. As soon as the thumb-lever is released, the spring automatically restores the bolt and its connected parts to original position. upon the self-closing of my sash-lock, which is accomplished as follows: In lowering or closing fully the inside sash, theilever, by its arm f2, strikes against the incline face g, caus ing the lever to turn to one side sufficiently to prepare the bolt c (when it strikes against the sh oulderg) to completethefull movementon the part of the lever; to clear the incline face and the'spindle-connections, and to withdraw itself clearof the catch G. This done,the springlocks the bolt, and restores all parts to locked condition. The lever must be turned to one side to open the sash-lock, and this can only be done from the inside; but in fully closing the inner sash, the sash-lock automatically closes or locks itself.

qW'hat I claim iS- 1. The improved sash-lock, consisting, essentially, of the casing A, having spindle b, the arm-connections D D `to bolt c, forming part of which is the bearing-plate c, having slot c2, the spring E, the catch G, having socket g3, to operate as and for the purposes set forth.

2. The improved sash-lock consisting of the4 casing A, having vspindle b, the arm connections D D, the bolt c, its bearing-plate c', having slot c2, the spring E, the thumb-lever F, having arm f2, the catch G, having socket g3,

mortise at g, and bevel-face at g, by meansv I lay stress IOO IIO

In testimony of said invention I have hereunto set my hand.
